penance.

a citizen of the United States, residing at Verona avenue and Oratonstreet, Newark, New Jersey, United States of America, have inventedImprovements in Machiner for the Manufacture-of Conical Tubes of aper orthe like, of which the following is a specification.

The objectof this invention is to provide or like material. In thespecification'of United States Patout No. 1020165 dated March 12th,1912, a

machine is described in which the cut blanks are placed, on a revolvingplaten or table, but in the present invention. the pan in which theblanks are placed does not rotate, and

- a single base, I stood that a single set only may be employed suchblanks are taken therefrom and operated on inan entirely diflerentmanner, as

will be seen by the following description taken in connection with theaccompanying drawings, in which:-

Figure 1 is a plan view of the machine;

Fig. 2 is partly a longitudinal section and partly 'a side elevationthereof.

Fig. 3 is partly a transverse section and partly an end' elevationthereof. Fig. 4 is a sectional'view of the head carrying the rollingmechanism, and

Fig. 5 a plan view thereof;

Fig. 6 is a sectional'view of the delivery arrangement, and i Fig. 7 asectional view of suitable means for controlling the air suction.

For the sake of clearness various unessential details have been eitheronly indicated 3 or entirely omitted from these drawings,

which illustrate whatmay be termed a dou ble machine, there being twocomplete sets of pasting and rolling mechanisms mounted on but it willbe readily underor that if desired and found advisable three or more ofsuch sets may be mounted on a single base. I p

in carrying out the present invention a driving shaft 1 is mounted inbase 2 and has motion imparted thereto in any desired manner. A bevelpinion 3 is mounted on shaft 1, and as shown in Fig. 3 transmits motionto twobevel Wheels 4: and 5, which, being mounted one above and onebelow the drivingshaftl, rotate in opposite directions.

Specification of Letters Patent.

' the rolling of The bevel wheel l, mounted above the driving shaft, isrigidly connected to a horizontal gear wheel 6 which is employed ashereinafter described to drive the pasting and rolling cones or mandrelsand also carries or has connected thereto or mounted thereon a num-Patented Nov. .5, 101%.. Application filed December 5, 1916. Serial No.135,196.

her of cams by which various operations are The second bevel wheel 5,mounted below the driving shaft 1, is carried by the central verticalshaft 7 of the machine. This shaft rotates in bearings carried by ahollow 'column 8 mounted in any suitable manner on the base 2, andcarries at its upper end a double armed pusher 9, to which it imparts acontinuous horizontal rotary movement.

The pusher revolves in. a pan 10mounted on a holder 11 carried at theupper end of the central column 8, the bottom of such pan,

upon which the blanks to be rolled are placed, being inclined downwardtoward the center at the same angle as it'is desired to form the conicaltubes.

A. thin strip of metal 109 is secured to the under side of the pusher 9and supports the 1 rear end of the pile of blanks which are pushedaround the pan by suchpusher;

The holder ,11 carrying pan 10 is capable of a slight up and downmovement on the upper end of column 8, any tendency to rotation beingprevented by the key 12. This up and down movement may be efiected byany suitable means, as for example that shown in the drawings andconsistingof a short sleeve 13 securely attached to the upper end ofshaft 7 and having trunnions or bearings for a pair-of rollers 14.Extending over these rollers 14 and secured to the holder 11 is a camsions by resting on the rollers 14 support the holder, so that as thelatter cannot rotate the inclined surfaces of'the cam will permit of therollers passing thereunder, thus lifting the cam and consequently alsothe holder 11 and. pan10. Such pan has, in the case of the doublemachine illustrated, two slots 16 arranged diametrically opposite each"otherin its under surface, these slotsbeing of'suficient width to allowof the widest blank for which the pan isto be used to pass freelytherethrough, and of suficient length (clrcumferentially of the pan 10).to permit the cones-or mandrels 17 on which 15 whose projections anddepres the blanks takes place to enter.

far enough for the upper surface of the mandrel to come in contact withthe under surface of the lowermost blank in the. pan.

As will be more fully hereinafter described, the mandrel 17 beingperforated and connected with an air pump or the like, on thus coming incontact with the lowermost blank draws the latter downwardly, thusseparating it from the next blank. As such' mandrel is beingcontinuously rotated it commences to roll up such blank and by-so doingbrings it to the position where the paste is applied, which is effectedby the following means The machine illustrated being a double one, twohollow standards 18 are mounted on the base 2 in suitable positions, andwithin these standards removable columns or sleeves 19 are supported inwhich are carried bearings for vertical shafts 20. The lower ends ofshafts 20 icarry pinions 21 gearing with the gear 6 hereinbeforereferred to, and their upper ends carry bevel pinions 22 gearing withcorresponding pinions 23 on horizontal spindles 123 to which paste cones24 are also secured. The cone 24 rotates in a aste reservoir 25 carriedby the upper end of the column 18, the spindle 123 of such cone runningin suitable bearings 'in the paste reservoir and being provided with'ahand wheel 26 by which the whole machine may be operated for trial,adjustment and the like purposes. At its inner end spindle 123 isprovided with a slip clutch 124 which allows the machine tobe rotated ina backward direction for adjustment without rotating the paste roller 24in a backward direction.

During its rotation the paste cone 24 takes up paste from the reservoir25, and this paste it transmits to a pasting plate 27 carried by asleeve 28 which has a hearing at its lower end on the elongated hub ofgear 6, and at its upper end on the holder 11 carrying pan 10. Thesleeve 28 is caused to rotate by a key 29 slidably connecting it withthe hub of gear 6, and is also capable of up and down movement throughthe intermediary of a cam 30 mounted on the base 2 of the machine, suchcam 30 acting on rollers 31 carried in trunnions on such sleeve. It willthus be seen that as gear 6 revolves it will rotate sleeve 28 and withit the pasting plate 27, while the action of cam 30 will be to raise thesleeve and plate at proper intervals into contact with the under surfaceof paste cone 24, which will apply paste to the plate as thelatterpasses beneath it. In its lower position the pasting plate 27 isat the proper [height for taking paste from the paste cone 24.

The" pasting plate 27 is of similar shape to butpreferably slightlysmaller than the part of the blank to which paste is to be applied, andthe surface of such plate is also preferably finely corrugated incircumferenti allines, or etched in a sort of checker board pattern.

-The mandrel 17 on which the blank is rolled is timed to bring theforward edge of the blank to the under side of the mandrel applied tothe whole of the desired portion .of the blank.

In the double machine shown it will of course be understood that eachpasting plate 27 receives a supply of paste from each of the paste cones24, and applies the paste to a blank on one of the mandrels of each setof rolling apparatus. i

As is clearly shown in Fig. 5 each set of rolling apparatus comprisesthree mandrels 17 on which the blanks'are to be rolled, but althoughthree is suitable it is not desired to limit the use of the machine tothis number. These mandrels are carried by hollow spindles '32 supportedby a head or casing 33, to which an intermittent rotary movement isimparted by any suitable means, for instance that shown in the drawings,which is as. follows The head 33 is carried by the upper end of a.sleeve 34 (see Fig. 4) supported by a column 35 mounted on the base 2 ofthe machine, and the lower end of such sleeve 34 carries a disk 36having three radial slots 37 into each of which in turn a roller 38carried by the gear 6 enters as the latter revolves. The roller 38having entered one of the slots the continued movement of the gear 6will cause the rotation of disk 36 until it is brought to such aposition that the roller can leave the slot it entered.

This will bring the disk 36 and conse quently the head 33 to theapproximate position for the next mandrel 17 of the set to be ready forthe reception of a blank, but it is important that the parts be stoppedand held in the exact position required, and with this object the springactuated lpcking pin 39 is employed. This pin is supported in the baseof column 35 and its spring normally holds it in holes 40 formed for itsreception in the disk 36. When however the disk is about to be rotatedthe pin is disengaged by means such as those shown, consisting informing angular teeth 41 on one side of the pin, with which engagesimilar teeth on a sector 42 on the arm of a double armed lever 43, theother arm of which carries a roller 44 acted on by a cam 45 formed on orsecured to gear Wheel 6. As the first cam begins to act on the roller itlifts the pin 39 out of hole 40 and so releases the disk 36,

incense at which can then make its intermittent movement (a third of arevolution in this case), andat or about the completion of this movementthe roller passes off the cam permitting lever 43 to turn, therebyallowing the pin 39 to enter the next hole in the disk 36, and so holdthe latter and the head 33 in position.

During the operation of the machine all the mandrels 17 are continuouslyrotated. This may be effected in any desired manner, but that shown inthe drawings is suitable and consists in the employment of a tube 46passing through the sleeve 34, and carrve j ing at its lower end apinion 47 engaig 5. 3 with the gear wheel 6, while at its upper'end abevel wheel 48 is mounted, such bevel wheel engaging with .acorresponding bevel wheel 49 mounted on the hollow spindle 32 of each ofthe mandrels.

The spindles 32 of the mandrels 17 are made hollow so that air may bedrawn therethrough to create suctionthrough perforations formed in themandrels 17, for the purpose of holding the forward edges of the blankson to such mandrels. lln constructing the machine for the purpose ofattaining this object the spindles 32 may as shown in Fig. 4 connect attheir inner ends with a chamber 50 in head 33, communicating with eachof the three mandrel spindles. This chamber 50 is connected by a tube 51passing through the tube 46 just previously men-- tioned to a chamber 52in a casting 53 carried on a rod 54 mounted in the base 2 of themachine, and which chamber 52 also communicates through tube 55 with avacuum pump or the like.

In order that the suction may be cut off when not required, or when therolled blank is to be released from the mandrel 17, a valve 56 is placedat the entrance to the chamber 50in head 33, and is acted on by a spring57 which tends to keep it closed. Such valve is mounted on a rod 58passing through the tube 51 and havingteeth at its lower end, where itpasses into the chamber 52, such teeth being acted upon by a sector 59(see Fig. 7) mounted on a spindle 60 to which is also connected a lever61 carry- .ing a cam roller 62 which at the proper times is actuated bya cam 63 on the gear wheel 6,

To assist in keeping the blank in contact with the. mandrel 17 bothduring and after the pasting of such blank, one or more rollers isarranged to press on each side of the mandrel during the operation, suchrollers being arranged and controlled in the following manner Eachroller 64, 64* (or two or more rollers if it is found desirable toemploy more than one on each side of the mandrel) is carried in a frame65 pivotally carried in an arm 66 mounted on a s indle 67 passingthrough a boss 68 on the casing or head 33 of the rolling mechanism. Onthe other end of the spindle 67 is a lever 69 provided with a roller 70which is held againsta cam 71. or 72 by means of a spring 73, the actionof the spring 73 being to cause the roller or rollers 64, 64 always tobear against the mandrel 17, while the action of the cams 71, 72 is to1s movable and only comes into action at the completlon of the rollingoperation as hereafter described, its motlon being obtained by mountingit as shown on a spindle 74 carried in bearings 75 (extending from thehub of cam 71) and 76 (in the base of column 35). The spindle 74 passesthrough the bearing 76 and has secured to its lower end a lever 77, onthe other end of which is mounted a roller 78 pressed into engagementwith a cam 79 on gear wheel 6 by means of a spring 80.

As will be seen in Fig. 5 the cam 71 keeps the rollers 64, 64 away fromthe mandrels 17 until one of the latter approaches the position fortaking a blank from the pan 10, the direction of movement of the set ofrolling mechanism being that of arrow 81. The rear roller or rollers 64of this particular mandrel will close down onto the latter as its camroller 70 runs down the incline 82 (shown in dotted lines in Fig. 5) ofcam 71, but the forward roller or rollers 64 will be still kept away toprevent them from coming in contact with the pasted blank until thetaking of the blank from pan 10 has been completed and the set ofrolling mechanism begins its next movement, when the cam rollers 70 oftheforward roller or rollers 64 will permit the latter to immediatelyclose down on the mandrel and remain down until the movement of the setof rolling mechanism to the position for delivery is almost completed.

blank, thus freeing such blank so that by the continued operation of themachine it may be removed from the mandrel.

This delivery is effected in the following manner :A tube 83 is disposedso as to be opposite the end of the mandrel 17 when the latter is in thedelivery position, and such tube 83 has a reciprocating movementimparted to it so that it passes over the mandrel while the latter isstationary. At its inner end such tube is split so as to form a spring,and a ring or catch or catches 84 is or are provided which owing to thisspring action will pass over the rolled blank, but 011 the returnmovement of the tube will hook behind such rolled blank and pull it offthe mandrel.

The reciprocating movement of the tube 83 may be obtained in.anysuitable manner, the arrangement shown in the drawings consisting inoperatingsame by a toothed rack 85 adapted to reciprocate in a guide way86, such rack engaging a pinion 87 on the upper end of a shaft 88 soported ina standard 89 mounted on the base of the column 35. On thelower end of shaft 88 is mount- I ed a pinion 90 engaged by a sector 91on one arm of a double armed lever 92, the other arm of which carries aroller 93 acting against a cam 94 on gear wheel 6, the roller 93 beingheld against the cam by means of a spring 95. It will be seen that ascam 94 rotates it will permit the spring 95 to draw the one arm of lever92- inw-ard, thus also operating the other arm of such lever the sectoron which engages pinion 90. The rotation of the latter will in turnrotate pinion 87 which by its engagement with rack 85 will reciprocatethe latter and also coneration the next blank will of course entertheone previously rolled and will be' nested therein, pushing thepreviously rolled blank further along the tube, and this will berepeated a ain and again until a suflicient length 0 rolled blanks hasbeen accumulated to be removed by hand.

As the pressure rollers 64 must be raised from the rolled blank beforetube 83 begins to pass over mandrel 17 while it is desirable that suchrolled blank should be held onto the mandrel as long as possible toprevent it from opening out again, means are preferably provided forholding the blank down until such tube is passing alongthe mandrel.

For this purpose a pair of disks 96, one above and the other below themandrel 17, may be provided, such disks being mounted on bent rods 97carried in bearings 98 at the top of the standard 89. A small lever 99is secured to each of the rods 97 and one' arm of each of these leversis acted on by a spring 100 in such a manner as to cause the disks 96tonormally bear on the rolled blank on mandrel 17 when the latter hasbeen brought to the delivery position. The other .arms of the levers 99project toward the tube 83 and carry at their-ends rollers 101 which liein the path of a double cam plate 102 secured to such tube, these partsbeing so arranged that in the inward movement of tube 83 the cam 102will operate to separate the rollers 101 and so lift both disks 96 awayfrom the rolled blank immediately before the end of tube 83 reaches theposition of such disks. As tube 83 moves outwardly again the disks willclosetoward each other and so be in position to hold the roll blank onthe next mandrel 17 whn the latter arrives at the delivery position.-

The operation of the machine as a whole is as follows :The machine shownbeing a double acting one, two' piles of blanks must be placed in thepan/l0, in position to be operated on, one by each arm of the usher 9,which rotates in the direction of t e ar- -row 103.- A supply of pasteor other adhesive is placed in each of the paste reservoirs 25, and themachine being started can continue running as the subsequent operationsof feeding the blanks thereto, supplying the adhesive; and removing therolled blanks can be atteiided to Without sto ping it. The pushers 9push the piles of blanks around in pan ,IO, and as the forward edge ofeach pile reaches the slot 16 the air suction through mandrel 17 (whichmandrel at this time will be practically lying in the slot as the pan isin its lower position) will draw and hold the lowermost blank of thepile, and as the upper surface of the mandrel is traveling in the samedirection and at the same speed as the pile such blank will be free towrap itself around the mandrel, the movement im arted by the pusherpreventing any liability of the blank being pulled away. from thesuction openings in mandrel 17. The edges of the slots in pan 10 are soshaped that only the blank actually acted on by the suction will betakenfrom the pile, the next blank being retained in the pan, even if it hada tendency to hang downwardly, by an upwardly inclined surface at thefurther edge of the slot.

After the blank has been 'drawn out for about one-fourth of a revolutionof the mandrel it will pass under the first pressure roller or rollers64: and this will assist the suction in keeping it on the mandrel anddrawing it from the pan.

When .the forward edge of the blank arrives at the under surface of themandrel (the latter having turned about half a revopasting plate 27which at this time is in its .upper position. Such pasting plate istraveling in the direction of the arrow 104:, that is to say in theopposite direction to the pusher 9, but in the same direction and at thesame speed as the under surface ofmandrel 17 carrying the blank. Thelatter and the pasting plate will therefore remain in contact during thecontinuance of the move ment, and consequently the paste will be appliedevenly to the desired portion of the blank, such plate bein as beforestated of the same shape but s ightly smaller than the portion of theblank to be pasted.

As the mandrel completes about threelution) it will meet the forwardedge of the lltl all

till

d ll

eanne fourths of a revolution it carries the pasted tion after thepasted inner layer of the blank has passed it.

One or more complete revolutions may be made after the whole of theblank has been rolled on the mandrel, so as to set the adhesive andobviate as far as possible any chance of the blank unrolling itself as aresult of the springiness of the material of which it is composed.

lln the meantime the pan 10 will have been raised to its upper position,so that when roller 38 on gear 6 enters one of the slots 3'2 in disk 36,to bring the next mandrel 17 to position for receiving a blank, themandrel carrying the rolled blank will be free to turn to the deliveryposition, passing between the disks 96 which are then in the position toexert pressure on the rolled blank and which do so until the deliverytube 83 has nearly reached them. The pressure rollers 64:, 643 must ashereinbefore stated have been lifted from the rolled blank before thedelivery tube begins to pass over the mandrel.

As the delivery tube reaches the inner edge of the rolled body its catch84: passes down behind such inner edge, so that on the return or outwardmovement the rolled blank will be drawn 0d the mandrel; the latter willthen be ready to be turned to its next position bringing the followingemandrel with a rolled blank ready for delivery opposite to the tube 83.

A machine constructed as above described can be readily changed toenable diflerent sized tubes to be rolled. lff such tubes are to be ofthe same diameter at their larger end it will not be necessary to changethe pan 10, which however, must be replaced by another of difierent sizeif tubes of larger or smaller diameter at their larger ends are to berolled.

It will be readily understood that the invention is not limited to theprecise details shown, as these may be largely modified in many wayswithout departing from the spirit of the invention.
